A chamber filled with N₂ molecules is at a low pressure of 48 Pa but high temperature of 800 K? If there is a small hole of diameter 3.0 mm on the wall of the chamber, how many N₂ molecules would effuse out per second? It is known that the molecular weight of N₂ is 28. Also recall that the area of a circle is xr², where r is the radius. Note that the answer is a big number. Submit the answer in E notation, e.g., 5.4x1012 should be entered as 5.4E12. Round the coefficient of the answer to one decimal place. Hints: 1. The number of molecules effusing out of a small hole per second is known as the effusion rate. 2. The effusion rate is the product of the molecular flux and the area of the hole. 3. Find the formulas in the notes of Unit 2.3 to solve the problem.
